You have the right idea, but your completely made-up numbers are not even close --- the standard is 80% capacity after 500 cycles at the normally specified (1C) charge rate. If my vague recollection of the last time I read about this is correct, at 2C (twice as fast), after 500 cycles the capacity remaining may be more like 20%. It's definitely nonlinear.

Heres an "entry" article: https://kabru.eecs.umich.edu/wordpress/wp-content/uploads/St...

and you can follow the references from there (into SciHub etc. if need be.)

Discharge depth is far, far more important.
